ABSTRACT:
A method of producing nitrogenated metal alloys which involves melting a al alloy under a nitrogen atmosphere and subsequently gas atomizing the molten alloy with nitrogen gas has been found to produce alloys powders having a high nitrogen content and a minimum amount of hollow particles. The resulting alloy powders which demonstrate superior mechanical properties and heat and chemical resistance are easily fabricated into articles utilizing powder metallurgical processes.
